ABSTRACT:
A casing for storing an airbag forming part of an airbag restraint system in an automotive vehicle. The airbag storing casing comprises a main body formed of a material including (a) a thermoplastic elastomer composition in an amount of 100 parts by weight, the thermoplastic elastomer composition being prepared by a process including mixing 10 to 50 parts by weight of a polyolefin resin with 100 parts by weight of an olefin copolymer rubber to obtain a mixture, dynamically heat-treating the mixture in the presence of an organic peroxide, and then adding 5 to 50 parts by weight of a mineral oil relative to 100 parts by weight of the dynamically heat-treated mixture, the olefin copolymer rubber having a Mooney viscosity (ML.sub.1+4, 100.degree. C.) ranging from 50 to 100, and (b) a random copolymer resin in an amount of 20 to 50 parts by weight, containing propylene and at least one kind of 1-olefin other than propylene and having a Melt Flow Rate (230.degree. C.) ranging from 30 to 100. Additionally, a paint is coated on the surface of the main body and includes a resin component including chlorinated polyolefin resin, a modifier including alcohol-modified silicone and polyhydric alcohol, and a hardener including a mixture of an addition product of hexamethylene diisocyanate and polyester polyol, and hexamethylene diisocyanate.
